Title: Casing for shaft excavation
Inventor: MIYAZAKI KAORU
IPC: E21B7/20
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To economize the consumption of steel members and increase the safety, by making thin a shaft casing and increasing the strength by a reinforcing means. SOLUTION: The thickness of 12-16 mm in conventional circular casings is reduced to 4.5-6 mm. And recesses 6 are formed from the outside face to the inside of the steel pipe by a press. In this way, concentration of stresses can be prevented by smoothly shaping these recesses 6. A grab bucket can pass the inside without outside caught of the recesses 6. As there is no projection at the outside face of the easing 3, clamp bands can be fitted on the smooth casing 3. In this case, the recesses are made smaller than half of the width of the clamp band 7.

Title: Cold trap
Inventor: TAKAHASHI SHIYOUNOSUKE
IPC: B01D8/00
Filed: 1981-12-09
Abstract: PURPOSE:To prevent the entry of reacting gases in a vacuum pump and the corrosion of the pump by passing the corrosive reacting gases to a cold trap provided with an annular inside tank to be cooled with a cooling medium in the inside and sticking the same on the inside walls thereof. CONSTITUTION:In the stage of reducing the pressure of the chlorine reacting gases in a semiconductor producing device with a vacuum pump to react, the reacting gases sucked into the vacuum pump corrode the vacuum pump. In order to prevent such corrosion, a cold trap is disposed between a reactor under reduced pressure and the vacuum pump. The reacting gases flow through an inlet 12 into the cold trap, pass through the space delineated by the annular inside tank 3 cooled with a cooling medium such as liquid nitrogen and partition walls 4, 5 and are sucked into the vacuum pump through a discharge port 13. During this time, the reacting gases condense and stick on the tanks 3 and the walls 4, 5, and the quantity that the gases enter the vacuum pump decrease considerably and the corrosion of the vacuum pump is prevented.

Title: Data transmission system
Inventor: HIDAKA HITOSHI
IPC: H04B1/40
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To give the aural guidance only to a relevant visually handicapped person by receiving the data from a data transmitting device, notifying the reception of data in voices at least when the reception of data is started or ended, and storing and then outputting the received data. SOLUTION: A receiving part 11 receives a header signal of the voice data from a transmitting/receiving device 1 and notifies a controller 16 of the start of reception of the voice data. Based on this notification, the controller 16 instructs a voice reproduction part 12 to output an optional electronic tone to notify a user of the start of reception of the voice data. When all voice data are received and the header signal is also received, the part 11 notifies the controller 16 of this reception of both data and signal. Thus, the controller 16 instructs the part 12 to output an optional electronic tone to notify the user of the end of reception of the voice data. As a result, the user can know the start and end of reception of the voice data by those electronic tones.

Abstract: PURPOSE:To enlarge a dynamic range measurable by using high output laser, by mounting a means for performing the samplings of reflected light levels several times in the time receiving reflected light with respect to one optical pulse signal to a means for analyzing received reflected light. CONSTITUTION:A light mixer 2 guides the output light of an optical fiber 3 to be tested to a photoelectric converter 4 from the output end thereof only during a time T2 and cuts off the inputting of the signal from an input end to the optical fiber 3 to be tested. As a result, as shown by Fig C, scattered light generated in the optical fiber 3 is penetrated to be inputted to the photoelectric converter 4. Signal input is performed to the input of the photoelectric converter 4 only during the time T2 while signal input is not performed in the other time and, therefore, a signal noise ratio can be improved. The output of the photoelectric converter 4 is amplified by an amplifier 9 to be inputted to a treatment circuit 10 where, with respect to scattered light received during the time T2 as shown by Fig C, the scattered light levels thereof are repeatedly sampled at every about 400nS (nano sec). About 400nS corresponds to about 40m of the optical fiber from the optical signal propagation speed in said optical fiber.
